To all whom it may concern Be it known that 1, JOHN W; l-lasntrns, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have'invented certain new and useful Improvements in Glass-Washing Machines, of which the following is aspeeificat-ion. D

My invention relates to. improvements in glass washing machines, and in someof its features articularly to a machine for washin fiat'g ass lates. v

The genera object of m inventlon is to provide a machine arrange to receive stacks of plates and to automatically perform the operation of thoroughly washlng each plate.

In the drawings, wherein I haye illusof my invention,

tral vertical section through the washing chamber and appurtenant parts.

. In thedrawings, 10 indicates in general a supply reservoir to receive the stacked plates 11, said reservior consisting of a hotmounted in the side members 13 tom plate 12 prefe ably arranged at a sumciently oblique an le to the horizontal to cause gravitationaldescent of the stack of plates 11, side rails 13, and top guides 1.4 upwardly deflected as at 15 near the rear ends to facilitate introduction of the plates intothe reservoir. The bottom, member 12 of the reservoir forms the top member of a washing chamber to be described, and has therein at an appropriate point a transverse slot 16 forming a suitable openingto permit the passage of a single plate at a time from the reservoir into the washing chamber. The stack of plates 11, slipping gravitationally down the reservoir as indicated, is stopped by ing inwardly from side wall melnbers 13, carried by bottom 12, the endmost or lower plate of the stack being held by said stops 17 and the pressure of the plates above it directly in register with the aperture 16. The plates 11 are fed opening 16, one'at a time, by the operation feed arm 19 having mounted telescopically in its ends a feed finger20, said arm 19 being fast on a transverse shaft 22 and 'arranged to be rocked-by mechanism to be described;

The washing chamben' generally indicated: at 25, is preferably a rectangular casing;

top, boaam, and side walls, and a front end 27 indicates a drive shaft traversing the casing and carrying an exterior driving pulley28. Shaft 27 carries a large gear 29 meshing with a corresponding gear 30 upon the second'shaft 31 traversing thecasing. Interiorly of thelcasing'the two shafts 27 and 31 respectively carry driving rollers 32 and 32' for corresponding conveyer belts 33 and 33""by which movement of the plates through the cleaning chamber is effected and controlled. The belt 33 is preferably of rubber, over upper and lower idler rollers 34 and 35, and across the face of a flat table. 36, extending between, the idlers 34 and 35, and at its sides secured as at 37 to, the side walls of the casing. The belt 33 is arranged in similar fashion (like arts being indicated by like numerals clistlnguished by the ex- L7 ponent prime), but the belts are oppositely arranged for successive coaction respectively with opposite sides of the late in transit through the cleaning cham er. I The beltguiding rollers 34 and 35 are respectively confronted by the idle guiding rollers 38 and 39, and the extremities of the table 36 are preferably opposed by a same relative i with reference 1said driving, belts and their opposing idle irollers, there is providcda plate path extending in alinement with the plate-receiving aperture 16 of the casing top continuiously throughout thecasing to a delivery point at pair of smaller rollers 40 (the arrangement being carried out to the belt 33), so that by the bottom thereof. Manifestly, a plate fed to the upper belt is assed downelt, as indiof the beltsgiving' them continuous control of the plate of the proper size'throughout Opposing the table 42, mounted on a shaft 43 and arranged to sweep over the surface ofthe plate as it passes through the plate path described, the direction of rotation qf the brush being preferably such that its surface in contact with the-plate moves in the direction of platemovement, though at a higher speed than that at which the plate is moving.

1 ing of a single plate therefore occurring with Wall of the casing,'1s provided with a pinion by gearing asdescribed, from the shaft3l. Each brush 'actsn on a'p'ortion of the plate which is ade uate y supported by the table with the drying chamber 56' on which the The use and operation of the device will reservoir 10 are fed by means of arm 19 and shaft 43, projecting beyond the appropriate 46, meshing with a gear 47, carried by the shaft 27, the gearing relation being such as, to produce peripheral movement of the brush at a greater velocity thanrthe velocity of belt movement imparted through said shaft 27 to the belt 33.

The brusharrangement described is duplicated with respect to brush 42, driven,

underlying t e conveyer belt, so that the plate is held u to the brush and breakage In order that the automatic feeding of the plates 11 from the reservoir into. theplate path of the-washing chamber may always occur at proper "time intervals under. any

range the rock shaft '22 for the feed arm 19 to be driven by cranks connected by arms 51 with eccentric straps 52 engaging eccentrics 53 mounted on shaft 31; the feedeach rotation of shaft 31, and the belt'move ment concurrentwith such rotation of the shaft being such'that movement of at least a plate-length occurs between feeding ac tions. Thus, one plate is fed to the washing chamber and'one plate delivered therefrom for'each revolution of the drive shaft: 27 and its companion shaft 31, Now, it will be manifest that each plate passed through the plate'path is acted upon first on one side and then on" the other by the companion brushes supplied'with cleansing fluid from their respective pipes, the surplus fluid being led off through the outlet 4:9 at the lower corner of the washing chamber. I The plate path leads at itslower end to a transfer chu'te55, preferably provided with rubber. squeegee blades 55' at its mouth and opening through the bottom of the washin chamber to communicate at its. lower en washing chamber is carried as. by suitable braces 57. 4

nowbe apparent. Theplates stacked in the longitudinally-yielding finger- 20 one by one through the, opening '16 into the washing chamber, each plate being received by the upperbelt 33,and fed downwardly first by the upper belt, andthen by the lower belt, through the plate path, to the" transfer chute 55. In its traverse through the washing chamber, first-one side and then the other side of the plate is subjected to the washing action of the appropriate brushes, said brushes being constantly supplied with cleansing fluid thereby thoroughly to wash the plates. The feeding operation takes place once in every revolution of'the main shaft 27, and correspondingly, one 'plate is delivered into the. transfer chute 55 for each revolution of the shaft, the arrangement enabling two plates to be in .transit through the washing chamber at the same time.

While I have herein described in some having an inlet for a plate of glass to be washed and an outlet opposite to said inlet;

two duplicate,oppositely-facing non-alining plate engaging and feedingymeans, each comprising a conveyer belt, having astraight plate guiding run, a belt driving 'roller at the rear thereof and a stationary table underlying the plate guiding run; a rotary plate scouring brush, in front of the straight plate guiding runof each""of .the feeding means; intermeshin gears, carried by the belt driving rollers,

wliereby they are rotated at the same speed; a gear, carried by each of the scouring brushes; and a gear,

associated with each roller driving gear and meshing with its opposite brush driving ear. 1

smaller than the second afore' mentioned gear, carried by each of the-scouring brushes and eachmeshing with its opposite second mentioned gear, whereby the peripheral velocity of the scouring brush is greater than.

that of the belt driving roller.

In testimony wherof I hereunto set my hand in the presence of twowitnesses.
